Neanderthal genes still influence modern humans

Recent studies have found that Neanderthal genes comprise between one and four percent of the genome of present-day humans. However, how much those genes are still actively influencing human traits has largely remained a mystery. 
Now, a multi-institutional team of researchers led by Cornell University has developed a set of computational genetic tools to clarify the genetic traces of interbreeding between humans of non-African ancestry and Neanderthals that occurred about 50,000 years ago. 
The analysis revealed that, although some Neanderthal genes are responsible for certain traits in modern humans - including several with a substantial influence on the immune system - modern human genes seem to be winning out over successive generations.
